Led Lenser K4R.2

The Led Lenser keychain flashlight is a mid-budget solution released in 2024. The model combines maximum compactness (body length 5.2 cm) and lightness (only 20 grams) with decent luminous flux indicators. Thus, the model supports 3 operating modes that differ in brightness - economical, balanced and powerful (enhanced Boost). Their luminous flux is 20, 60 and 120 lm, respectively, and the lighting range varies from 10 to 30 meters.

The Led Lenser K4R.2 flashlight is powered by a built-in lithium-polymer battery, which should provide from 1 (at maximum brightness) to 3.5 hours (at minimum mode) of autonomous operation. And the subsequent charging process is carried out from the built-in folding USB A connector. Thus, the keychain, like a flash drive, can be connected directly to a power adapter (without wires), as well as a laptop, power bank, etc. Note that the model's body is made of aluminum with a practical matte finish, but without special protection from atmospheric influences (IP2X). A practical metal carabiner is provided for attaching to a bunch of keys, a backpack, a bag, etc.
